>>39611607>Darkrai is the living embodiment of nightmares that killed a little girl in BW2. It's a moldy cinnamon roll made out of shit and sandpaper.The same thing happens with Yveltal, it is the personification of death itself, but even Pokédex herself says that he does not want to do this, it is simply his nature, he even had to confine himself on a distant island so that humans do not succumb to the Nightmares, Yveltal doesn't kill either because yes. If he doesn't, he will eventually die.
>it just eats dreams to surviveEat dreams =/= kill, in fact, in Japanese mythology, Baku was considered a kind entity because when eating dreams, it turned away nightmares.
